' Stitches for Fastening Buttons, of which the following description, in connection with the accompanying" drawings, is a specification, likel letters on the drawings representing like parts.

My present invention is a novel form of Vlock loop-stitch, especially valuable and useful inv sewingV buttons, either on clothing or cards 1 I have herein illustrated'the novel forni of lock loop-stitch, comprising my invention in connection with the carding of buttons, such carding having-heretofore been done eitherf by hand when thread was employed or bywire where a machine was utilized., such, 'for'eXample, 'as shown by my prior Patent 1,055,523, dated March 11,1913. In fastening 1 buttons by wire, especially on cards from which'A the buttons were intended to'- be removed subsequently, the wire card- Ying is unsuited' for certain uses,'as thebuttons had to be removed individu-ally from the card to which they were secured when wanted for use. As suclrcards usually contain a dozen buttons, it `has been usual for tailors and other users of such buttons, to cut off an entire4 row, or theV entiredivision of buttons with-a single sweep of a knife, but this was not feasible where wire-was used to fasten them, and hence some delay was involved in removing such` buttons when fastened by wireV staples or the' like. Therefore, securing such buttons especially to sale cards by means of thread i'sdesirable. The objection toT carding Aby thread `has been that such carding was necessarily done by hand, and also that the entire series of rows of buttons on a card (usually four rows `of three buttons each) `were secured Vby a single thread so that if it was desired to use only one row ofbutton's, and these werecut olf from the card, allthe others would fall off. Furthermore, such hand Work involved putting in va knot at both start and nish,which knot atthe end could not be made snugly to the cardand tightly drawn and consequently all thef buttons on card were'somewha't loosely held* The eXpense:` andf'time required for and only a single thread was used to hold the blittons to thel card which" was aptto break, pull through, and not hold the buttons securely.

l havedevised a machine vcapable of carding buttons withv thread, said machine being described and claimed in my copending application `Serial No. 72,054 liled January l-l, 191G,`whi`ch .machine is capableof 'carding buttons bythe novel form of lock loopstitch herein shown and claimed.` l My lock loop-stitch enables each button to be firmly secured by a doublet/bread, to be individually fastened to the card, and to permit either the entire set ofbuttons on a 'card to be cut off by the single sweep of the knife., `or one row to be cut oli4 while `all the others are firmly retained on`ftliefc`arcl,"or a single button to be "removed without the other `buttons falling off orr their fastenings being loosened. Furthernioreymy present invention eliminatesthe necessity for" knotting either-end of a thread `when'carding or sewing buttons, butlocks each button, as well as each end of a thread uniting' a `row of buttons, as the stitch is formed. A further advantage of my novel ,form of loop stitch is that l may employ "the same to sew a single button onto clothing,locking each stitch untill an entire predetermined length of thread is used up, and should one stitch break, the remainingstitches are individu- 'ally locked andheldlirinlyinplace; Astill further advantage 'of present novel forni of lock loop-stitch is that, although each stitch will be locked,` yet a positive knot may be formed at the end of the thread for the last button or stitch, andlalso a positive knot maybe formed atl the-`Co1npletion of each stitch by withholding the feeding movement of the card and buttons, and permitting` the shuttle mechanism to Complete the looping action, as more fully explained `in my saidcopending application, illustratcross section and reverse side a button card with one row having a knot put in the thread at each stitch; and

Figs. 6 and 7 illustrate in cross section and reverse side respectively the combination of loop-stitch with a knot at the end of the thread on one row.

The button card 1 is usually of thin cardboard or heavy paper through which a sewing` needle may readily pass, either by machine or by hand, to which the buttons 2 are secured in rows. My novel form 0f loopstitch may be put in either by hand or by machine, preferably the latter', as illustrated in my copending application above 1nentioned, such thread 3 being a double thread in suiiicient length when doubled to secure t0 the card the series of buttons in a row. As herein illustrated, I show the buttons secured in rows of four each, the buttons 2 being a usual form of clothing button, with slightly cup shaped 0r depressed centers, pierced with a plurality of holes l1. The thread 3 is passed through two opposite holes 4: of each button, forming a loop 5. Starting with the first button, at the right `viewing Figs. 1, 2, and 3, the doubled end of the thread 3 is passed upwardly through the card 1, and the opposite holes 4 in the button 2, to make the loop 5, and both ends of the entire remaining length of thread are passed through the ends 6 of the loop 5, and pulled tight- The loop end 6 thus encircles both the threads 3, which thereby jam the same against the card 1 and constitute a lock loop-stitch, as will be clearly understood on reference to Fig. 2. The thread 8 is then led through an adjacent point in the card 1, preferably the card l being fed a distance slightly greater than the diameter of the buttons being carded, when a second loop 5 is passed upwardly through the card 1, and holes 4 in a second button 2 and downwardly again through the card 1, both ends of the thread 3 being caught in the second doubled portion 6 of the loop 5, and drawn taut, thus again locking the next stitch and holding the second button firmly to the card, locking the thread stitched, securing the same independently of the iirst buttonl loop. The loop-stitch last described is again repeated on successive buttons until the entire series of the row and the length of thread employed therefor has been used up. My novel form of loop-stitch thus secures and locks each button holding stitch independently of the adjacent button, and one or more buttons may be cut off without the remaining buttons falling from the card, or an entire row or the whole set may be cut from the card by a single sweep of a knife. Each button is held firmly, securely, and by a double thread, and it is unnecessary to form a knot ,in the end of the thread, although this may be ydone if desired, as will be hereinafter explained. I am thus enabled to secure the buttons, by means of thread, permitting all the advantages of severing the same from the card quickly when de sired for use, as well as equally obtaining the advantages of carding by wire staples, securing individually each button to the card and permitting one or more buttons to be removed without the remaining buttons falling from the card.

In Figs. et, 5, 6, and` 7 I have illustrated aslightly modified form, wherein the same loop-stitch is employed, but showing how a positive knot may be formed in the thread 3, either after each button has been stitched, or after the entire series or rows of buttons have been stitched. Such a knot is desirable in special cases of work, heavy buttons and the like. As illustrated in Figs. et and 5, the buttons 2 are first secured by the loop-stitch already described, then the thread is given a second turn by the rotary shuttle, as eX- plained in my said machine application, thus forming a positive knot 7, said knot comprisingI a double loop, as more clearly illustrated at 8 and 9, where the double loop is shown before the ends of the thread are pulled tight. In this modified form a slightly longer length of doubled thread 3 may be necessary to allow forthe plurality of knots being' formed at each loop-stitch.

In Figs. 6 and 7, I illustrate the combination of the loop-stitches as shown in Figs. 1, 2, and 3 for each of the first three buttons 2 in the series, and a knot 7 at the end of the thread on the last button. This form is the preferred fastening because of the added security of the knot preventing any slipping of the thread and consequently loosening of the loop-stitches, during handling, packing, shipping, etc., of the carded buttons.

While I have herein illustrated my novel form of loop-stitch as of special value for the cai-ding of buttons by thread, and as the machine of my said copending application is designed primarily for carding buttons by making the lock loop-stitch and knot, herein described, and it will be readily understood that it may be desirable for other machines to form such a lock loopstitch in sewingl buttons to clothing, I believe that the lock loop stitch herein disclosed, utilizing a double thread and securing a rm locking stitch each time such stitch is made, is a distinct novelty in the art, and I wish to claim the same broadly. Also carding buttons by thread which will secure said buttons independently to the card, enabling one button a coined phrase to describe` my novel form of stitch made `with adouble thread, wherein both ends of the thread are caught, engaged and held in a locked manner as each stitch is made, which locking effect is sulficient so that one stitch can be cut Without loosening the adjacent stitch or stitches.

Having described my invention, What I claim as new and desire to secure by Letters Patent is:

l. A seam for seWed articles, comprising a plurality of articles to be stitched toegther, a doubled thread of predetermined length constituting the thread utilized in the seam, each stitch of said seam being formed with a loop on one side, and with both ends of each stitch locked on the loop side of said articles. v

Q. As an article of manufacture, a button card provided With a complement of buttons, a seam uniting said buttons to the card, consisting in a predetermined length of doubled thread, each stitch including a thread loop passing through both card and button with the ends of the thread of each stitch locked on the underside of the card.

3. As an article of manufacture, a button card provided with a complement of buttons.l each button having a plurality of perforations therethrough, a seam uniting said butopies of this patent may be obtained for tons to the card, consisting in a predetermined length of doubled thread, a loop in said thread passing through at least tWo of the perforations in each button, and said seam locking both the ends of the thread in each button-holding stitch under a loop in said seam.

4. As an article of manufacture, a button card provided with a complement of buttons, each button having a plurality of perforations therethrough, a seam uniting said buttons to the card, consisting in a predetermined length of doubled thread, a loop in said thread passing through at least two of the perforations in each button, and said seam locking` both the ends of the thread in each button-holding` stitch under a loop in said sea-m, one of said threads completely encircling the parts of both button and card united by each stitch and being locked by the loop of said stitch.

ln testimony whereof, I have signed my naine to this specification, in the presence of two subscribing Witnesses ARTHUR L. CURRIER.
